The best time to measure ketones is in the morning after fasting through the night. This is when ketones are at their lowest, which will give you a true measurement. If that's not possible, just be sure to measure your ketones at the same time everyday so you can observe patterns. Remember, it's ideal to have ketones between 1.5 and 3 to achieve optimal fat-burning. If you are using the Precision Xtra blood meter, make sure you have purchased the Ketone testing strips and not the strips for blood sugar.
